Big brim blind rivets

Blind rivets with large brim: Compared with ordinary blind rivets, the diameter of the aluminum cap of this rivet is significantly larger. When the rivet is riveted with the connector, it has a larger contact area and a stronger supporting surface, which can enhance the torque strength. Can withstand higher radial tension. Applicable industry: suitable for soft and fragile surface materials and the fastening of extra-large holes. The increased brim diameter has a special protective effect on soft materials.

Precautions for big brim blind rivets

1. When checking the finished large brim blind rivet, check: rivet body diameter, rivet body length, rivet body cap thickness, cap diameter, total length of mandrel, exposed size of mandrel, size of nail cap, and outer diameter after assembly .Consider. In the actual inspection, the weak links of the product can be measured, such as: tensile force, shear resistance, core-pulling resistance.

2. The point is to pay attention to the rivets. If the rivets are insufficient, whether they are riveted in place; or because the cap of the mandrel is too large, the mouth of the rivet body cannot be pulled down; the fracture size is too small, etc.

3, Rivet material: aluminum, iron, stainless steel, alloy, etc.

4. The total thickness of the workpiece is generally 45%--65% of the length of the rivet, not higher than 60%. In addition, the working length is too short, it is more troublesome, in general, it is recommended to take 50%--60%. The length of the rivet is too long, the rivet If the head is too large, the nail rod is easy to bend; the length of the rivet is too short, the thickness of the pier body is insufficient, and the formation of the nail head is incomplete, which affects the strength and tightness. The length of the rivet is too long or too short. Riveting effect.
